Answer:
diameter =7 cm
Step-by-step explanation:
circum=2pi×r

2×pi×r=22
2×22÷7×r=22
r=22×7÷44
r=7÷2
r=3.5
d=2×r=2×3.5=7
Answer:

Answer:
A=pi
Step-by-step explanation:
The formula of the area of a circle is A=pi*r^2 where r=radius.
In this problem, you have radius of 1 meter. So just plug that into the equation and solve for the area.
A=pi*(1)^2=pi*1*1=pi*1=pi
A=pi
Answer:
i think the answer is ( C )

<u>Step-by-step explanation:</u>
When you plug in 3 directly to the equation, you get 0/0
Since it is indeterminate, you have to use L'Hopital's Rule.
That means that you find the limit of the DERIVATIVE of the numerator and the DERIVATIVE of the denominator.
